To all whom it may concern:

Be it lmown that l, HENRY Russ, a citizen of the United States, residingat Sedan, in the county of Chautauqua and State of Kansas, have inventedcertain new and useful improvements in Gas-Well Valve Structures, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This inventionv relates to a valve structure for use in gas wells andone object of the invention is to provide a valve structure which may beused. in connection with a gas Well and will serve to cause water whichnormally accumulates in the bottom of the gas well to be forced upwardlyand out of the well., At the present time no means is pro vided 'forremoving water from a gas well except by what is known as blowing thewell. -When a gas well is blown, and under present conditions this isnecessary every i-ew days, a large quantity of gas escapes but with theuse of this improved device the blowing of the well is not necessary andtherefore the gas, which, at the present time, is lost during theblowing operation, is saved.

This invention is illustrated in the accompanying drawings, wherein z-Figure 1 is a longitudinal sectional view through a portion of a gaswell showing the improved valves in use.

Figure i? is a longitudinal sectional view through one of the valves.

Figure 3 is a transverse sectional view taken along line 3-3 of Figure2.

This improved valve structure is for use in connection with a gas wellwhich will be provided with the usual casing 1 and tube 2 which extendsdownwardly through the casing 1 in spaced relation to the walls of thecasing. At the lower end of the tube there has been provided a packer 3which will be iirmly held in place and have tight engagement with thewalls of the tube so that gas and water passing upwardly through thetube must pass through this hollow packer. A pipe 4f extends downwardlythrough this inner tube and is provided with lower sections 5 and 6, thesection 5 being connected with the main bod of. the pipe 4 by a valvehousing 7 and wit the lower section 6 by means of a valve housing 8. Thelower section 6 has its lower end connected with a valve housing 9 whichrests upon the packer 3 and has close tting enga ement with the upperend of the packy er. t will thus be seen that the as and water must passupwardly through t e low er sections 5` and 6 and valve housings inorder to reach the outlet pipe 4. The valve housings are of asimilarconstruction and each is provided with a cylindrical body having itslower end portion internally thickened as shown at l0 to provide areduced passage and a concaved valve seat 11 at the upper end of thethickened portion. A ball valve 12 is placed in the body for normallyseating upon the valve seat 11 and preventing gas and water from passingdownwardly through the passage in the lower end portion of the valvebody. Upward pressure will raise the valve ball so that the gas andwater may pass upwardly but when the pressure decreases the valve ballwill seat upon the valve seat and prevent downward movement of the gasand water. A pin 13 extends transversely through the valve body abovethe valve balll so that upward movement of the valve ball is limited.

When this device is in use the pipe 4, having the lower sections 5 and 6and valve members 7, 8 and 9 connected therewith, is lowered inthe'inner tube of the gas well until the lower valve casing 9 rests uponand forms a tight joint with the packer 3."

The distance from the upper end of the packer to the valve seat l1 ofthe lower valve member 9 will be approximately twenty-hive feet, thedistance from the valve seat of the lower valve member to the valve seatot the second valve member 8, approximately one hundred and titty (150)feet, and the distance from the valve seat 11 of the second valve 8 tothe valve seat of the upper valve' member 7, approximately two hundred(200) feet. The distance between the lower valve member and theintermediate valve member 8 and the distance between the intermediatevalve member and the upper valve member may, however, be varied bysimply providing pipe sections 5 and 6 of diii'erent lengths, if it isfound necessary, in order to produce a better working device when inuse. As the water tends to accumulate in the bottom of the gas well thepressure of the gas will force this water upwardly through the innerpipe and valves associated therewith and as this water must pass throu hthe valves as it moves upwardly throug the pipe, it will be preventedfrom returning to the bottom of the well. Therefore, the water will belgradually lifted in the pipe 4 until it reaches such a height that itcan be drawn oil' through the medium of a drip system. lt will thus beseen that by means of this arran ement of valves the gas well, eventhong the Water accumulates rapidly, may be kept free of water Iand nogas is lost by a blowing operation.

l. In a as well, a casin a tubingtherein spaced rom the walls t ereoi, atubular packer fitting snu ly within the tubing, an outlet pipe incluing a pluralit of sections, valve casings connecting t e successivesections, the valve casings and outlet pipe sections being s aced fromthe wall of the tubing, and the owermost valve easing seating upon saidpacker, each valve casing being formed internally with a shoulderolening'a valve seat, and an upwardly opening valve upon each seat.

2. ln a Well, a casing, a tubing therein spaced therefrom, a resilienttubular packer within and iitting snugly against the tubing, an outletpipe spaced from 'the wall ot the tubing and formed of a plurality ofsections, a plurality'o cylindrical valve casings secured onto theadjacent ends of the plpe sections a similar valve casing at the lowerend o the lowermost section fitting upon the upper end of the packer,each valve casing being formed internally with a valve seat, a ballvalve within each casing normally resting upon the seat, and meansWithin each casing for preventing engagement of the ball valve with thelower end of the pipe section.
